TO DO list:
* Puff system.
* Check fast NOx calibration data.
* Start CO2 on autosampler #1.
* Calibration tank for enclosures.
3 flights from 3:30am (local time) to breakfast. First two flights with O3 sonde only (clear gradient from ~10 to ~30ppbv). Third flight with bags as well to collected ambient air samples. Bags analyzed by Catie on TOF.
CO2 sensor connected to enclosure. Started collecting data around 3pm local time. Logging every 60 seconds.

I checked HOBO data.
Detlev made changes to the method yesterday (BVOC_SCAN_SIM_190531.M): the oven stays at 120°C between samples now and decreases to 35°C when the run starts (the lower we go, the better the earlier peaks such as isoprene are). Today, we increased the max temperature of the method to 260°C instead of 250°C. Note that we did not change the method’s name, still BVOC_SCAN_SIM_190531.M.
Today we updated the SIM time segments:
We also updated the peaks for each segments:
* alkanes + CFC-11: 41, 43 (alkanes) 101, 103 (CFC-11).
* isoprene: 67, 68.
* CFC-113: 101, 151.
* metacrolein + MVK: 41, 55, 70.
* aromatics (benzene, toluene, xylenes): 78, 91, 106.
* MT: 68, 93, 121, 136.
* SQT: 204, 91, 93, 119, 69.
TL_20190601_01.TL_20190601_02 is NPL.Kaixin and Jacob collected ambient air samples in 4 different bags. Catie analyzed them on the TOF.
